Hello,
after application, they’ll probably ask you to pass the numerical and data interpretation exams. If you are good enough, they’ll invite you to a short video interview. Shouldn’t last longer than 10 minutes. Next stage is the selection day that is based on a brief presentation on a random topic. Subsequently, it’s time for the case study. You’ll have 30 minutes to prepare before you must present. This part is tough. Afterwards, a last short interview.
So wish you more luck than I had. ;D
